At 305 angstrom wavelength, the sun presents in a red orange with the monstrous flare flowing on the lower right side in this SDO image. X-class flares are the strongest class of solar storms the sun can experience.

This animation of the sun on Sept. 6, 2017, displays the X2.2 and X9.3 flares radiating outward. The flares erupted from an extremely active sunspots, known as Active Regions 2673 and 2674.

Two large sunspots are visible on the right side of the sun, in this image taken by the Helioseismic and Magnetic Imager (HMI) on NASA's Solar Dynamics Observatory, which shows magnetic activity on the star's surface. The image was taken on Sept. 6, 2017.

Using both visible and 304 angstrom extreme ultraviolet wavelengths, both sunspots on the surface and the flare in the sun's atmosphere are clear.

This image from the SDO shows a combination of views of the X9.3 solar flare. On the left a blend of 131 and 171 angstrom light is shown and on the right both visible and 304 angstrom extreme ultraviolet wavelengths are shown. The righthand image clearly shows the flare in the solar atmosphere as well.

The sunspot responsible for the X9.3 solar flare did show some early signs of its power. On Sept. 4, 2017, the M5.5 class solar flare, shown in 131 angstrom wavelength, flashes near the center of our giant star.
